I have an Application Load Balancer whose data transfer cost I want to monitor.

In Cost Explorer, I can filter on usage type "DataTransfer-Out-Bytes", and see how many GB of data it is sending, and how much that costs. However, it only shows the total for each day, and the data is delayed by several hours. In order to see how the amount of traffic is affected by changes I make, I'd like to see that same number in CloudWatch, but I can't find any corresponding metric.

The Per-AppELB "ProcessedBytes" metric sounded promising, but that number is slightly more than half the number I see in Cost Explorer. (My best guess is that TLS handshake overhead isn't included.)

Is there any metric or combination of metrics that matches what I end up getting billed for?

I just got this bounce message:

<████████@att.net>: host scc-mailrelay.att.net[204.127.208.75] said:
    521-88.208.246.34 blocked by sbc:blacklist.mailrelay.att.net. 521 DNSRBL:
    Blocked for abuse. See http://att.net/blocks (in reply to MAIL FROM
    command)

So I'm trying to figure out why our server ended up on their blacklist. The web page link doesn't tell me why, as far as I can see. From a few multi-RBL tools I conclude that our IP is only on the collateral damage lists of uceprotect.net (you can be exempt from that with a paid subscription), and I dearly hope that AT&T doesn't use that.

From the mail server logs I see that an email to another @att.net address went through two days ago without being blocked.

Does anyone have any ideas how I can find out what went wrong?

In Redmine 0.8.2, I want changeset information fetched automatically, instead of only when someone views the Repository tab of the corresponding project. (I need this so that commit messages containing "refs #42" or "closes #42" have effect as soon as possible.)

The crontab of the user that Redmine runs as has the following entry:

# m h  dom mon dow   command
*/5 * * * * ruby /var/www/redmine/script/runner Repository.fetch_changesets -e production

This used to work prior to a server migration, and it works from the command line (as the Redmine user), but it doesn't work from cron. I can see in the syslog that the command is run:

Feb 15 14:05:01 turing /USR/SBIN/CRON[24119]: (www-data) CMD (ruby /var/www/redmine/script/runner Repository.fetch_changesets -e production)

but the database isn't updated. There are no entries in the Redmine logs.

I got this snippet from the Redmine FAQ. I see that the suggested command has been changed to:

rake -f /path/to/redmine/Rakefile redmine:fetch_changesets

but when I run this from the command line it doesn't pick up the configuration, and thus gets "access denied" when accessing the database.

Which alley should I go down? What obvious thing am I forgetting to check?

cron redmine
